Welcome to Woodminster Amphitheater!High in the Oakland hills, overlooking the San Francisco Bay and the cities on both shores, Woodminster Amphitheater is at the heart of historic Joaquin Miller Park. The Amphitheater, and the pools and cascades below it, were built as a WPA project and dedicated in 1940 in honor of California writers. Today, the city-owned facility has had some improvements to make it safer and more comfortable for modern audiences, but it is still a charming, rustic, outdoor performance space.
